NAME

       fgetws - read a wide-character string from a FILE stream

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <wchar.h>

       wchar_t *fgetws(wchar_t ws[restrict .n], int n, FILE *restrict stream);

DESCRIPTION

       The fgetws() function is the wide-character equivalent of the fgets(3) function.  It reads
       a string of at most n-1 wide characters into the wide-character array pointed  to  by  ws,
       and  adds  a  terminating  null  wide character (L'\0').  It stops reading wide characters
       after it has encountered and stored a newline wide character.  It also stops when  end  of
       stream is reached.

       The programmer must ensure that there is room for at least n wide characters at ws.

       For a nonlocking counterpart, see unlocked_stdio(3).

RETURN VALUE

       The fgetws() function, if successful, returns ws.  If end of stream was already reached or
       if an error occurred, it returns NULL.

NOTES

       The behavior of fgetws() depends on the LC_CTYPE category of the current locale.

       In the absence of additional information passed to the fopen(3) call, it is reasonable  to
       expect  that  fgetws()  will  actually  read  a  multibyte string from the stream and then
       convert it to a wide-character string.

       This function is unreliable, because it does not permit to deal properly  with  null  wide
       characters that may be present in the input.
